Which of the following orbitals is not possible (in $f$)?

Which one of the following configurations represents a noble gas?

The number of $d$ electrons in $Fe$ is equal to which of the following?
$i$. Total number of '$s$' electrons of $Mg$
$ii$. Total number of '$p$' electrons of $Cl$
$iii$. Total number of '$p$' electrons of $Ne$
The correct option is

$(i)$ An atomic orbital has $n=3$. What are the possible values of $l$ and $m_l$?
$(ii)$ List the quantum numbers ($m_l$ and $l$) of electrons for $3d$ orbital.
$(iii)$ Which of the following orbitals are possible? $1p$,$2s$,$2p$,and $3f$.

Match the columns and choose the correct option:

Column-$I$	Column-$II$
$(a)$ $4s$	$(p)$ Circular orbit around nucleus
$(b)$ $4p$	$(q)$ Non-directional orbital
$(c)$ $1s$	$(r)$ Angular momentum $= 2h/\pi$
$(d)$ $3d$	$(s)$ Radial node is zero

Give the symbol of the element with the lowest atomic number that has three $2p$ electrons.
